TECHNIQUE OF SIGHTING Russian patent published in 1997 - IPC

FIELD: technique of enhancing of fire effect, in particular, technique of sighting. SUBSTANCE: angle of sight visual field at shooting a guided missile is decreased from initial value β₀ down to estimated value β₁ after measurement of the range, and after the guided missile is brought to the aiming line it is decreased down to estimated value β₂ at angular velocity β′. At the instant when the guided missile reaches the target the angle of visual field is increased up to initial value β₀. The minimum value of the angle of visual field is limited proceeding from the following condition: β_min≥K_s(B_t+l_dr/D_t.max),, where K_s - safety factor; B_t - maximum linear dimension of target; l_dr - preset drift of guided missile from aiming line; D_t.max - maximum target range. EFFECT: enhanced fire effect. 1 dwg
